I need to load an action sheet on a GLSprite derived game. I tried adding a UIViewController but when I display the actionsheet none of my touches are registering, and I can't figure out how to close the action sheet and switch the view back to my game? Should I only create a UIViewController when its needed, or all of the time? Rath...

I'd like to use a UIWebView with the same typographical appearance as the rest of my app texts which all use [UIFont systemFontOfSize:15]. But before doing some forensic research maybe someone knows what font that really is? ...
This has me really confused. I'm working on a custom animation for rotating an image inside a custom UITableViewCell. This all works fine when I place the code inside the same class as I'm calling it from, but fails if I put the code in it's parent.

I have subclassed UITableViewCell to make a custom cell for a tableView. I add text and images to the cell's contentView. Everything looks great in landscape mode (iPad), but no so much when I rotate to portrait. Where is the best place to handle orientation changes so that all the table cells can reposition the contents in its contentV...
Reading acceleromenter data is quite easy on the Iphone but using them effectively to simulate a virtual joystick is a different story. I see that accelerometer data are quite noisy and the average module of each axis accelleration in a rest position is not comparable. I wonder if the most effective way to use accelleromenter is to look ...

I just came across this article that mentions both Microsoft and Apple have banned all GPLv3 based code from their mobile "app store"-related sites. http://www.zdnet.co.uk/reviews/developer-tools/2010/09/27/windows-phone-7-developer-tools-a-first-look-40090296/ excerpt: "The one unfriendly part of the agreements you need to sign ...
I am in this situation where I have to display a button which says "Open myApp" (if myApp is installed on the device) or it says "Download myApp" (if myApp is not installed on the device) in an iphone app. To do this, I need to detect whether an app (with a known custom URL) has been installed on the device. How can I do this? Thanks in ...
I have a scenario where it's possible to earn > 1 achievement at the same time. Has anyone come across a good solution for displaying them using OpenFeint? Right now OpenFeint shows 2 overlapping each other -- not that helpful for the user. I'm wondering if OpenFeint has a built-in system for handling this, rather than having to write...
I have a list of items I'd like to show in a UITableViewCell. Right now, I'm simply using a cell.textLabel with commas separating each value, but I'd like to do something a little more dynamic. How would I achieve something like this? Would it be an array of UILabels with borders and radius on those borders? Thanks for your ideas. ...
How can I get which language an app is running on? And I don't mean the preference set into settings! Let me explain it further... I localised my app with three languages: English, Italian and Spanish. If the iPhone is set on Italian or Spanish, the app will use those two... it falls back to English otherwise. For example: a French use...

Anyone have any idea why CGContextFillPath won't work in the code snippet below? I'm using the following code to draw to a UIImageView. It's stroking the path correctly, but ignoring CGContextFillPath.

When I initially load my view there is a spinner and "Loading..." label displayed. However, after my data is loaded, the spinner and label appear on screen for a good 2 seconds.
